1)Your job is to design a new toddler bouncer-chair for Amazon toys. Research shows toddlers prefer a 2.0 second period of up and down motion. If the toddler size is 10.0kg, what should the chair’s spring constant be? 2) A bungee chair ride at Busch Gardens has bungees with a spring constant of 164 N/m. If the average load of rider and chair combined equals 150. Kg. What would be the period of the first up-and-down shot that riders experience.

3) The director of a new Tarzan movie wants a scene in which Tarzan swings from a tree limb to a small cliff in 2.5 seconds. Tarzan’s mass is 86 kg. How long a vine should Tarzan have to just make it to the edge of the cliff?

4) Home depot has hired you to design a backyard swing set for 7 to 9 year-olds. The chains holding the seat are 8 feet (2.44m) long. What would be the period of the swing that riders would experience?

Explanation:

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
